No sound on Ubuntu - HP Pavilion X2 Detachable

Hi, I have recently installed Ubuntu 17.10 on my HP Pavilion X2 Detachable laptop. There is no sound from the built-in speakers nor from earpods when plugged to the jack output. I followed the SoundTroubleShootingProcedure (https://help.ubuntu.com/community/SoundTroubleshootingProcedure) which didn't fix the sound.
